I've found that many dark, i.e navy, black smooth(crescent1500-17000) marr easily when rubbed together, or stored in board racks. The water trick works well, but when that fails, I use an opaline bag(scumbag) in the opposite direction of the scrape with moderate pressure, and it clears the mat, with up close scrutiny, even under glass, you might save a triple mat reverse bevel with a half geyner twist.
